Formula
π × (od − wt) × wt × density × length
Result unit: kg

Pipe weight = π × (OD − WT) × WT × ρ × L. The engine converts all dimensions to SI base units (meters). Density in kg/m³, length in meters, result in kg.

Introduction

Calculate pipe weight for steel, stainless steel, and alloy pipes. Uses the standard hollow cylinder formula: W = π × (OD − WT) × WT × ρ × L.

Calculation Example

A 4-inch Schedule 40 steel pipe (114.3mm OD, 6.02mm wall) weighs approximately 16.07 kg per meter.

Inputs: od=114.3, wt=6.02, length=1, density=7850
Result: 16.07 kg

Engineering Applications

  • •Piping design
  • •Structural support calculation
  • •Transportation and rigging
  • •Cost estimation

Frequently Asked Questions
